Gaming on the Find 5

Hello fellow Find 5 friends! ( say that 5 times fast :laugh: )
As we all know the Find 5 packs a:
Qualcomm S4 Pro APQ8064
Krait 200 CPU: 4 cores @ 1.5GHz
Adreno 320: 400MHz
2GB RAM @ 533 MHz dual channel

in its belly, and shares this with quite a list of phones:
Asus PadFone 2
HTC Droid DNA
HTC J Butterfly
LG Optimus G
Nexus 4
Pantech Vega No.6
Pantech Vega R3
Sharp Aquos Phone Zeta
Sony Xperia UL
Sony Xperia Z
Sony Xperia ZL
Sony Xperia ZR
Xiaomi MI-2
Panasonic P-02E
Note that some new devices (the Nexus 7 2013 is a good example) has a "S4 Pro" SoC in the spec sheet, but is actually a lower-binned / lower-clocked 600 chip [APQ8064–1AA to be exact] and uses Krait 300 CPU cores and therefore outperforms its Krait 200 cousins in the Nexus 4 / Find 5 / etc.
The silicon is quite formidable- and led pack until the release of Qualcomm's 600 and 800 chips. Although some argue that the Adreno 320 is slightly underpowered for 1080p, the point is the Find 5 packs alot of power.
However despite this custom ROM gaming performance was poor initially:
Entropy512 said:
Some games apparently hang the device. Others, such as Ingress, work perfectly.
Problem is our display subsystem is a really nasty hackjob that is a mix of early 4.1 source code (Oppo's original baseline) and 4.2 stuff. Ideally, it will eventually be a pure CAF jb2.5 branch baseline - this is what most other CM devices are on or going to. Some stuff is easy to rebase, some is harder. I have a feeling I'm probably going to fix the camera the same way as the Sony and Samsung guys did it - copypasta the entire camera subsystem drivers from the original baseline and use those. (The camera drivers in the kernel seem isolated enough that it works fine on Samsung and Sony qcoms.) Biggest thing is the power management, especially charging - Oppo made major changes here to Qualcomm's early-4.1 baseline, AND Qualcomm made major changes to this code. As a result, getting that stuff right and properly merged is gonna be a PITA. It's sort-of-barely working in the codebase on my personal github, but it's doing all sorts of stuff it shouldn't, and also not doing stuff it should (like charging from USB). The standby power drain is also insane, which is strange since the newer CAF codebase should be MORE power efficient, not less.

However since the 4.2 kernel rebase gaming performance has dramatically improved in my testing. This no doubt is related to all the kernel display changes work from our wonderful developers made possible by Oppo who released the sources for 4.2..
So pick up a ROM / kernel combination that has this 4.2 goodness and feel improvements across the board! Here is a list of the ROMs:
Color ROM [formerly known as Project Firefly] v1.0.0_33xx and later
Maxwen's AOKP 20130810 and later
CM10.1 Official Nightly 20130810 and later
CodefireX
IMPORTANT NOTE- CUSTOM ROMS USE THE 4.1 MODEM FIRMWARE
This means if you've flashed a 4.2 Color ROM and want to move to a custom ROM, you MUST flash the modem firmware from a 4.1 Color ROM before flashing a custom ROM or else WIFI WILL NOT WORK. Simply flash the 4.1 Color ROM (or the firmware package) and then flash the custom ROM immdediately after, you do not need to boot the 4.1 Color ROM.
Now back to the actual thread, I thought it would be helpful to compile a master list of games that work and don't work (for whatever reason) and use this as a future reference and for troubleshooting. Feel free to contribute: just the game name, your experience on it and if possible your ROM / kernel configuration.
My device settings:
Latest Maxwen AOKP / kernel
MP-Decision: Off
Multicore Power Saving: 0
CPU: 162MHz / 1.134 GHz
Governor: smartmax_eps
CPUQuiet: load_stats

EMULATORS
With the release of DraStic I felt it was time to add a section for emulators. I will list them by console rather than app.
DS
DraStic is my emulator of choice. I'll leave the feature list to the developer, but the biggest draw is that it is very fast. Since version 2.1.1a (released 8/1x/2013) the DS BIOS file is no longer needed for unencrypted ROMs. If my word (and the word of many across the internet) is not enough to convince you to drop $8, there is a demo version of the app (full functionality, 20 minute limit)
Some select quotes from the FAQ:
Q: Does DraStic support 3DS games? Will it in the future?
A: No, it does not and never will. 3DS is an entirely different system, a full generation ahead, like N64 to Gamecube.
Click to expand...
Click to collapse
Q: How fast should I expect DraStic to be?
A: It varies greatly depending on the game you're trying to run. A device with 1GHz Cortex-A8 will run many games with a fair amount of frameskip. A 1.4+GHz dual-core Cortex-A9 will run most games with little or no frameskip most of the time.
Click to expand...
Click to collapse
Q: Does it help to have multiple CPU cores?
A: Yes. If you have multiple cores DraStic is sped up by being able to offload screen update tasks to another thread. If you select the multi-threaded renderer option you will get even more benefit, but this option can cause graphical glitches and instability.

Click to collapse
Q: Are MOGA controllers supported?
A: It is possible to make it work by installing Moga Universal Driver from Google Play. We are currently working on including native support.
Click to expand...
Click to collapse
Q: Does DraStic use my GPU to render graphics? Does it help to have a faster GPU
A: The GPU is only used to scale the image and apply filters so having a better one won't make much difference. OpenGL ES is not used to render the Nintendo DS graphics. This is because of idiosynchracies in the DS graphics hardware that would make this style of emulation incomplete and/or slow.

Click to collapse
Q: Does DraStic support homebrew games?
A: Currently many homebrew games are not supported because DraStic does not yet support DLDI filesystem integration which many homebrew games rely on. This is a planned feature for a later date.

I have only played a few games (namely ones that have simple controls) and they have been flawless.
My settings:
Frameskip: Auto [4]
Filter: Scale2X
Multi-threaded 3D rendering: Off [haven't played a game that needs it]
Sound Latency: Medium [Low is the best quality but introduces some clicking in my testing]

Well I don't game much but even the lightest game I play, Rage of Bahamut, lags worse than on any other Handset I tried it.
Also I have to admit that on AOSP Roms even the interaction with the UI feels like there is something wrong with the phone. Compared to a Nexus 4 or a S3 or S4 the UI lags or slows down everywhere from time to time...

I don't play many games, in fact I only play Tekken Card Tournament. But since I have got my Find 5 the game always crash my phone, sometimes already after seconds.
Hope the devs will fix this soon and get the phone stable. Currently using cm10.1 and maxwen kernel.

Updated OP with some new findings and reports from other users and developers. Found a fix for the performance issues (ended up being an extension of a weird interaction I found)
Basically, if the game / application lags, turn the screen off and on again without exiting the application- upon resuming the lag should be gone!

House of the Dead
+ Playable, seem to run smooth at high fps.
+ Responsive controls.
- Random crashes (general game issue, not device or rom).
Street Fighter 4
+ Playable, high fps
- Audio feedback delayed

Gaming performance on color rom.is much better than previous roms

I have included a few CAF fixes in the display driver and would be
very interessted if they change anything in games that have issues

I have one positive report on oppoforum that with latest test
kernel games issues are gone
please give it a try and report back

that's great news, unfortunately for me I still get low frame rate, although it seems better than before.
screen off / on trick still works fine

I have to admit that I lost your last log somewhere
I would need both a logcat and a kernel log
simply attach your device via adb and run
Code:
adb logcat
adb shell dmesg
copy the output of both commands into a file and upload it

I think I'm doing something wrong- I have the device connected via adb, then I launch the game and start the logcat / desg (adb logcat < log.txt). The device hard reboots after about 10 seconds. After it finished I run (adb shell cat /proc/last_msg > kmsg.txt) to get the last_kmsg
Oddly the frame rate is actually better while connected to ADB and logging then normal (of course nowhere close to post screen on/off).

Well - the low framerate is because device is spilling to logs
and that slows down everything
Right now I am unable to identify a change in CAF that "could" fix this issue
Problem is also that I still dont have an easy way to reproduce this here
so I can not even do some trial-and-error things.

Of course I/O and CPU would be spent logging and frame rate would suffer, but when I was testing the FPS was actually higher than it is usually even with the logging in process- maybe because it was plugged in through USB?
Did I do the logs correctly? I don't know why my logs are so damn big!

Okay excellent, I'll install the free version, and report back in 10 minutes with a log if I see frame rate issues after a clean reboot, would that help?
I also suspect I have the Chinese version (seller wasn't clear)- according to Oppo there is only a band difference (1700)- but maybe thats a hidden confounding variable?

dont think so

Possibility of GPU OC @ more than 487mhz?

Well, as we all know, the the Adreno 320 on the s4 pro is barely capable enough for our device's resolution.
A lot of new games like Dead trigger 2 and Dead effect are struggling to provide decent framerates. Over clocking the cpu does not improve
anything. (I disabled thermal throttling to ensure the processors are not being throttled down)
So, we do need more Graphics prowess.
If thermal problems will arise by doing so, why don't we just UC the cpu and OC the GPU? Then do a mild undervolt.
Well, do you guys think the same as I do?
Will you not find it awesome to see devs implementing GPU OC of more than
487mhz? Or is it just not possible hardware wise?
Let's all talk about it here.
EDIT:
It seems like Riptide GP 2 is struggling as well, and it's not even at max settings..

Why don't you try download DT2 and repeat the steps above?
I assure you, the frame rates will be choppy enough for you to tone down the settings again.

Very high settings are clearly intended for a higher end phone then.

Oc a mobile phone should never be done. There is a reason why Qualcomm limits the CPU and GPU to those MHz and since that is almost the only thing that will break the warranty on find 5 I really hope oc as high as that won't happens. I really think that the oc that's made for now is as high as it should be and future improvements needs to be found else where

That's way to much I think , stock GPU freq is 320 MHz iirc always remember its a phone , not a pc also the limitations will be the SoC at the end but it should be able to improve a bit without a higher freq, will test that game again later on to see what freq I can do at that settings

Lag solutions

I've seen a good amount of people complaining about lag, so i thought i'd share what i've done to get my g3 running smoothly.
* See below for kernel settings
First off I rooted my d850 with towelroot. Using titanium backup, I froze all at&t apps along with apps I don't use like kindle, uber, beats music. Also froze messages back & sync since it was always running, and I backup up my texts manually.
Everything I froze:

Now there's the whole art debate. I have noticed a big improvement in smoothness and battery life using art, but there's also compatibility issues with some apps, and xposed. When switching back to dalvik runtime you can definitely see some general UI stuttering, here's what can be done.
Kernel settings
I installed (and highly recommend) Kernel Toolkit and played around with a few settings. You'll have to install busybox too which worked fine. KEEP IN MIND we don't have a recovery to save our asses in case of bootloops so if you make any changes in trickster do so at your own risk, and when using set on boot, apply a long enough delay for you to fix any bootloops in the event that your phone doesn't like your settings.
That being said I would be surprised if anyone manages to find settings that causes reboots on the stock kernel, given that theres no voltage table to mess up, or any unique cpu governers.
Onto my settings:
I/O scheduler = cfq
Governor control (with interactive governor) -> hispeed_freq = 1267200
Here are some other changes you can make in governor control for better performance:
go_hispeed_load - change from 90 to 85
min_sample_time - change from 40000 to 50000
target_loads - change from 85 to 80 or 75 (75 = better performance)
NOTE: I have tested my settings for a few days and they seem to be stable. If you want even better performance (at the cost of some battery life) you can try some more changes DON'T use the set on boot option until you're sure they don't cause reboots! Once you deem them stable you should use set on boot with a 30 second delay. Without the set on boot option you'll have to manually reapply your settings after every bootup as kernel settings get set back to default on boot.
NOTE: I've found using the ondemand governor causes reboots.
With these settings i'm not missing art anymore. I've found that setting the scheduler to cfq takes care of most of the lag. Keep in mind that tweaking the kernel for better performance USUALLY comes at the cost of a little battery life. So you'll have to find a sweet spot that your happy with in terms of performance and battery life. Feel free to discuss and share your kernel settings

I'm probably the only one experiencing more lag with ART than not. With ART enabled my G3 was stuttering everywhere and I had to pull the battery ~3 times in 2 hours because the screen just wouldn't turn on.
It's silky smooth on dalvik though, lol

Yeah sounds like compatibility issues with some of your apps.

Tested ondemand governor, caused reboots.

Surely a third party launcher will just sort all lag issues out?

Why would it do that? Of course it helps with launcher lag but not with lag occuring in menus etc.
Oh and thanks to Heisenberg! Tried your settings and with art enabled everything works nice and smoothly. No more stuttering.

Please let us know how stable these settings end up being. Thanks!

I think people are getting confused over what is lag and what is not.
Lag is when the UI is delayed when it shouldn't be - this can be caused by a number of factors including wrong cpu clock speeds, overheating or lack of quality ram management (usually due to one or two poorly coded apps eating everything up!)
What most of you are experiencing on Dalvik is not lag, its just the way the JIT compiler works, apps on Dalvik will take a split second to open while it compiles what it needs, generally speaking this is not noticable, but we all know people on XDA always notice everything....
If you are experiencing lag then it is most likely caused by something other than Dalvik the ART build on this device is outdated doesn't offer anything (seriously!) over Dalvik, this in no way reflects what we will see on Android L.

My g3 suffers terribly from redraw it just should not be happening on something this powerful

I had some noticable stuttering in many actions like in menus and scrolling. After changing to ART and enabling these tweaks they are gone. Placebo or not I'm happy with the results, no stutters or lag of whatever you want to call it I'm aware the ART included is nothing like ART on L, but to me it just helps that little bit.

That's placebo.
ART only affects lag, that is the time between pressing on an icon and the app opening. ART pre compiles the bytecode needed to run an app beforehand thus eliminating the need to do it on the fly which dalvik does (it should also improve battery life as converting it to bytecode takes cpu cycles). It doesn't do anything for stutter or scrolling. By yeah the ART in 4.4.2 is old code as well and not optimized yet so there will be little improvement in lag also.

So be it. It doesn't matter to me if its placebo or not. Feels nicer to use and that is what matters.

Still not getting the ART love. For milli seconds of improvement you lose 25% of storage space. Not seeing the net positive at all, but a big a$$ net negative.

I will miss Xposed if they can't get it to work right on ART

I'll try your guide. Lag and redraw is not what I prefer in a new flagship. Art is more than placebo, it's notable better but I'll like to use Xposed.

SadLy true

Seems to do some difference. Even with art I had some lag in app drawer and it seems to be gone. Placebo or not, it's feels a bit more snappy in app drawer so that's another one to beat the dust ? So far I'll keep art on, I have loads of space and launcher and apps are notable snappier with it in. Its not like my M8 but it's a bit closer.

art
Sorry for a very noobish question, but can someone tell me what art is? I got my lg g3 last week and quiet playing a bit with it. I got the international version 3/32gb (LG-D855 V10a) and wanted to root it to somehow boost my battery life. Its fine and my battery can last a day with my normal usage and im very happy with it (waaaaaay much better than my ip5), but if i can squeeze more juice and make it last a day and a half or even more, im willing to root and take full pledge over my device.
I also experience having error that my device is heating up and won't be able to max out brightness, weird coz when it happen im actually doing nothing with my device, i just adjust brightness and it wont let me to max it out, so as of now im considering it as a bug and hoping that an update will fix it. It does warm up a bit but not the same as my toasty galaxy note 2 and galaxy s4 so i can live with it, but if i can remove the energy being waste and boost battery life by rooting it, ill forget OTA.
Anyway, back to my main concern,,, what is art? Hue hue

Hey mate. Art is android run time. Do a quick google search on how to change it or one of the pro's on here can go into the finer details on the benefits of using it.

[TIP] Increase gaming performance

The N7 is an amazing tablet, but lets face it, the S4 Pro and Adreno 320 GPU really aren't up to the task when it comes to gaming on such a high resolution screen. Graphically intensive games just don't run as well as they should. So I did some digging and testing, and found an app that lets you lower your screen resolution, thus decreasing the strain on the GPU and increasing gaming performance. When changing the resolution to 800x1280, I found a noticeble increase in framerate in 3D games such as Riptide GP 1+2, NOVA 3, and Modern Combat 5, and the games still look great. You're not going to want to leave the resolution set that low all the time because it does make everything else look pretty bad, but when you're going to play a game, it only takes a second to set the resolution and start playing. It's a paid app (there are free ones that do the same thing, but I've had the best luck with this one), but considering the gains, it's worth every penny of the $1.99 asking price. Here's the link- https://play.google.com/store/apps/details?id=com.lugalabs.resolutionchanger
So, give it a shot and let me know how it works out for you.
Here's some before and after 3D benchmarks-

I wonder how this works? It appears you can change the resolution and the DPI seperately. I wonder if this has a development thread somewhere?
Resolution is a ridiculous game these days. 1080P on a 7" screen is crazy. I have 1080P on my 50" TV. The old Nexus 7 2012 had a great resolution for the size. Additional resolution is just wasted resources.
So you just changed the Resolution but kept the DPI the same? Does it do it automatically? Is this App specific or system wide? Does it affect normal desktop graphics?

All I did was change resolution, the app changed the DPI to 213 automatically when I changed the res. And it is system wide so it's not something you are going to want to set and leave at all times because you definitely can see it everywhere else. I change it before playing and change it back when I'm done.

My advice ist to use the phenomal Glitch Kernel, with that you can oc your GPU. This performance game perfomance is phantastic with 600mhz.

I generally like to remain stock nowadays, but I'll check out that kernel. You can't argue with that score.

I don't think our tablet is old for today's games yet. If the SoC was really an S4 Pro, than it would have come with an Adreno 320 which has 24 work pipes (something like parallel processor design which directly effects parallel processing and high resolution picturing, experts will explain better). But this SoC is actually a Snapdragon S600 which comes with a 32 work piped Adreno 320.
The S4 Pro is designed for 720p screens but this one is prepared for 1080p.
Besides, it's possible to OC it to almost 650MHz from 400 (the day this is necessary will come soon I guess).
PS: somehow lollipop seems to have trouble in games even though it is way better at everything else..

This came from necessity, I play a ton of games and the N7 doesn't handle the big ones as well as I'd like it to. I never would have looked into this if it ran them perfectly. But I am also 100% stock, so I haven't tried OC'ing the GPU. Honestly, last night when I did this the thought to flash a custom kernel and OC the GPU didn't even cross my mind.

What app are you using to change the settings? TricksterMod or FauxClock? Flashing the kernel now.
And what L2/Cache OC setting do you recommend?
Edit: I'm still on 4.4.4 and there's two options for the latest kitkat kernel- 226 and 226 disabled AVS, do you know which one I should flash?

This kernel comes with an Aroma installer, so you can set directly the settings you want during the installer. No need for a kernel manager app.
I recommend the settings that i get from Tk-Glitch, CPU 1,7 GHz with glitchy OC Bus, GPU 600mhz and undervolt-150mV.

They run fine, but some graphically intensive games don't have smooth framerates. Yours may be wonderful, but I know I'm not the only person on the planet that thinks there's room for improvement.

[Root Required] - Performance or Battery tuning Core_ctl

Intro
So this is a Guide that ive decided to make because ive found that you can get really good battery or really good performance by adjusting something called core_ctl, now Ive found that the z5's little cores NEVER turn off which in my opinion is silly so i decided to poke around and i found something called corectl and another called msm_performance.
im pretty certain this wont do any damage to your device as ive been playing with this since i got my z5 but there may be a performance hit and another note is that this SHOULD work on any S810 device or anything that has a big.little system.
Things Ive Learned
im going to note down things ive learned here that you shouldent do
- Do not Swap the big cores for the small cores using Is_big_cluster, it will cause repeat FCs and other issues.
- minimum of 1 big and 1 small core as it tends to become laggy without.
- Dont force off cores, if you want a core to turn off then use busy_up_thres or busy_down_thres
Requirements
you WILL need root and a filemanager like xplore unless you already know your way around a terminal emulator/adb
you Definately need a brain[emoji14]and just some time to read this obviously
this only works with the stock kernel or stock-ish kernels as of the moment.
Important Note
Before editing make sure everything is RW (Permission mode 744) and after editing anything be sure to change the permissions to read only (permission mode 644)
Core_ctl?
First of all these settings wont stick if you reboot so we will have to wait for Kernel Adiutor or an app alike to get updated.
anyway lets get started: you can find the parameter files in:
/sys/devices/system/cpu/cpu0/core_ctl/
(alternatively /sys/devices/system/cpu/cpu4/core_ctl/ for the big cores)
there will be 2 folders which will have this, cpu0 and cpu4. cpu0 is sort of the master core for the small cores and cpu4 is the master core for the big cores
(cpu0 to cpu3 are small)
(cpu4 to cpu7 are big)
editable files:
- busy_down_thres
- busy_up_thres
- is_big_cluster
- max_cpus
- min_cpus
Click to expand...
Click to collapse
busy_down_thres:
- Little cores
This file has a default value of "0" (looks like 0 0 0 0) (this is different for the big cores)
this means that if i change it to "25" when the cpu load dips below "25" it will then turn off cores, I recomend putting it at "40" (you dont have to change it to 40 40 40 40, you can just save it as 40)
( it seems the stock values for the big cores is fine with this)
busy_up_thres
If you havent guessed it, this does the oposite of the down_thres one, when your cpu load hits your set value then it will turn on cores, again this is defaulted to "0" for the little cores.
I have mine set to 50 for my little cores (i have left the default value for the big cores)
Is_big_cluster
this one is quite obvious but if you havent figured it out when set to "1" it then it will make the selected cluster (in this case little for example) take on heavier loads and act like the big cores
I dont recomend turning this to 1 as the little cores are little for a reason
max_cpus
this determines how many cpus within that cluster can be online at once
I recomend that you leave it at 4 as the little cores are quite weak but for the big cores you are fine to put it to 2 or even 1 if you want
min_cpus
This determines how many cpus MUST be online at once, I highly recomend that you keep 1 little core online as ive tried both with 0 minimum cores and ive had times where my device went total crazy and started lagging very bad
( you should be fine allowing 0 min_cpus for the big cores)
msm_performance
msm_performance is one of 2 (maybe more) hotplugs that the z5 uses with the stock kernel, there is msm_idle and msm_performance
there are some tweakable parameters in this so lets get started
you can find this in /sys/modules/msm_performance/parameters/
there is not much point to editing msm_performance as core_ctl is better to edit in my opinion
editable files:
- max_cpus
- num_clusters
(im pretty sure you can edit all of these but may be quite anoying to work with as they tend to reset them selves back to default)
max_cpus
so max_cpus is a global limit on how many cores can be on, it overrides what you'll find in the core_ctl but this has a habit of re-setting its self unless you change the permission mode to 644 after editing which is read only
when you open max_cpus you will see "-1:-1" this means any small or big core (e.g small:big), you can change this how ever you like, for example i recomend 4:2 or 2:2
num_clusters
this decides how many clusters you have, by default this is 2 because the snapdragon 810 has one small cluster and one big one, if you set this to 1 instead of 2 the big cores will act like any small core

Well, do you think that it would be possible to find a config as performant as stock but better for battery life ?

Works so far, so I made a small Tasker script that replace the "stock" files at every reboot with the modified ones

Nice write-up, thanks!
Though, this seems to be removed on current andro-kernel v26 so u might want to add that this is only available when running a kernel which includes this feature (like stock kernel as of now)

if you want better performance then make the big cores more aggressive when turning on and just have one small core, i tried this and it works out quite fine but gets you about the 4hrs SOT that stock gives

im pretty sure most Snapdragon 810 devices should be fine with these paths as i asked a freind with a nexus 6p to check if corectl was there and it is. im not too sure about /system/etc i usualy dont bother to look around there for stuff like this.

you may have to make some sort of script or use an app that copies modified versions for now untill an app implements the features required, i haved asked that this gets implemented into kernel adiutor but im not sure if that'll happen or not.
